Alpha-synuclein alters the faecal viromes of rats in a gut-initiated model of Parkinson's disease

S. R. Stockdale, L. A. Draper, S. O'Donovan, W. Barton, O. O'Sullivan, L. A. Volpicelli-Daley, A. Sullivan, C. O'Neill, C. Hill

This study shows that alpha-synuclein treatment in rats alters their faecal virome, with changes persisting over five months and influenced by LPS.

The role of arbuscular mycorrhiza and organosulfur mobilizing bacteria in plant sulphur supply

J. Gahan, O. O'Sullivan, P. D. Cotter, A. Schmalenberger

This study shows that arbuscular mycorrhiza (AM) symbiosis enhances plant uptake of organically-bound sulfur through interactions with hyphospheric bacteria that mobilize sulfate esters and sulfonates.

Fermented food metagenomics reveals substrate-associated differences in taxonomy, health-associated- and antibiotic resistance-determinants

J. Leech, R. Cabrera-Rubio, A. M. Walsh, G. Macori, C. J. Walsh, W. Barton, L. Finnegan, F. Crispie, O. O'Sullivan, M. J. Claesson, P. D. Cotter

This study uses shotgun metagenomics to analyze 58 fermented foods, revealing microbial composition, functional potential, and health-associated gene clusters across different food types.
